Well the Amlogic video decoders are still WIP.

There's a reason why there are currently no official LibreELEC 10.0 Amlogic releases.
I Know that. But the actual amlogic branch in chewitt's repo is well working. if MPEG2 hardware decoding would be usable it close to great. as i understand MPEG2 hardware decoding is there and needs to be enabled.
v4l2-ctl --list-formats-out shows: ioctl: VIDIOC_ENUM_FMT Type: Video Output Multiplanar
[0]: 'VP90' (VP9, compressed, dyn-resolution)
[1]: 'H264' (H.264, compressed, dyn-resolution)
[2]: 'MPG1' (MPEG-1 ES, compressed)
[3]: 'MPG2' (MPEG-2 ES, compressed)
MPEG-2 decoding looks like being there.
I would like to offer testing there, i have a wide range of amlogic plattforms ODROID-C2,C4,N2(+) and lepotato and further TV boxes. M
hardware MPEG2 decoding would greatly expand the usability .
We don't need testers or testing. We need developers capable of architecting and coding modern kernel drivers based on the emerging V4L2 APIs. There are not many who qualify, and since Amlogic has fostered zero "community" around their chips (for a long list of reasons) those who do meet the standard are professional developers who rightfully expect to be paid for their efforts. It will take $100k-$150k to complete the current VDEC work; which is not a huge sum, but also not the kind of pocket-change that people have laying around to spend on something with no clear business case behind it - that's the key to making something happen. I don't write code, so I'm powerless to personally "fix" the issues here, and while there are others in the wider LE team who have some of the skills needed, so much abuse has been historically directed towards LE team members taking an interest in Amlogic SoCs that people prefer to spend their time on other SoC targets where their efforts are praised not persecuted.
Thank you for pointing that out. I would like to support but unfortunately I 'm not able to code. Yes its a pity
Describe the bug
I'm running Chewitt's libreelec Branch amlogic on lepotato device. with the vnsi pvr addon. My issue that it shows for SD TV channels only a green screen, audio is working. all other TV resolutions in HD either 720p or 1024i are working well with hardware accel.
software decoding shows SD channels well.
To Reproduce
Steps to reproduce the behavior: switch to a SD TV channel

Additional context
How can a working hardware accel with MPEG2 decoding be used?
